Overview of this book

Exploratory Data Analysis (EDA) is an approach to data analysis that involves the application of diverse techniques to gain insights into a dataset. This book will help you gain practical knowledge of the main pillars of EDA - data cleaning, data preparation, data exploration, and data visualization. You’ll start by performing EDA using open source datasets and perform simple to advanced analyses to turn data into meaningful insights. You’ll then learn various descriptive statistical techniques to describe the basic characteristics of data and progress to performing EDA on time-series data. As you advance, you’ll learn how to implement EDA techniques for model development and evaluation and build predictive models to visualize results. Using Python for data analysis, you’ll work with real-world datasets, understand data, summarize its characteristics, and visualize it for business intelligence. By the end of this EDA book, you’ll have developed the skills required to carry out a preliminary investigation on any dataset, yield insights into data, present your results with visual aids, and build a model that correctly predicts future outcomes.

TSA with Open Power System Data

In this section, we are going to use Open Power System Data to understand TSA. We'll look at the time series data structures, time-based indexing, and several ways to visualize time series data.

We will start by importing the dataset. Look at the code snippet given here:

# load time series dataset
df_power = pd.read_csv("https://raw.githubusercontent.com/jenfly/opsd/master/opsd_germany_daily.csv")
df_power.columns

The output of the preceding code is given here:

Index(['Consumption', 'Wind', 'Solar', 'Wind+Solar'], dtype='object')

The columns of the dataframe are described here:

  • Date: The date is in the format yyyy-mm-dd.
  • Consumption: This indicates electricity consumption in GWh.
  • Solar: This indicates solar power production in GWh.
  • Wind+Solar: This represents the sum of solar and...
